A chink in bacteria's armor

Biomedical researchers at Boston University's College of Engineering may have discovered the path toward developing better drugs capable of defeating so-called “superbugs,” bacteria that have developed resistance to common antibiotics. The researchers have discovered a previously unknown chain of events occurring in bacteria that opens to door to new avenues of research.

Avocado extract stops growth of pre-cancerous cells that lead to oral cancer

Nutrients taken from avocados are able to thwart oral cancer cells, killing some and preventing pre-cancerous cells from developing into actual cancers, according to researchers at Ohio State University.

N-acetylcysteine may not be as safe as once thought

Certain preparations taken to enhance athletic performance or stave off disease contain an anti-oxidant that could cause harm.

Fat in the stomach may actually cause vitamin C to promote formation of cancer causing chemicals

The researchers analysed the impact of both fat (lipid) and vitamin C (ascorbic acid) on nitrite chemistry in the upper (proximal) stomach, which is especially vulnerable to pre-cancerous changes and tumour growth.

Fat: An active player in the regulation of many processes in health and disease

Why should we be interested in doing obesity-related research? Emphasis is put on this type of research simply because of the fact that the epidemiological data and predictions are alarming. Worldwide it is estimated that one person in every eight is overweight and more than 300 millions are obese

Patent foramen ovale (PFO) and atrial septal defect (ASD) closure

A PFO and an ASD are congenital structural heart diseases characterized by a communication between heart chambers at the level of the wall (septum) separating them. These chambers are the left and right atrium as shown on the picture below. The right atrium receives (dark) oxygen-depleted blood from the great veins, while the left atrium receives (red) oxygen-rich blood from the lungs.

Blood-flow detector software shows promise in preventing brain damage

Researchers from the Johns Hopkins Children's Center and Cambridge University in England have designed an automated means of continuously tracking potentially dangerous changes in blood flow to the brain in real time, a system that shows promise for preventing brain damage and death in children with head injuries.

Efficacy of non-invasive ventilation in patients with acute cardiogenic pulmonary oede

Acute cardiogenic pulmonary oedema, or "fluid on the lung", is a common, extremely distressing and often fatal condition that is a major consumer of health care resources. The aim of the 3CPO trial was to establish whether high-pressure oxygen, given by a simple facemask, could help reduce the death rate in patients with this condition.

Does physical activity provide a molecular key to longevity?

Fitness and physical exercise are among the most neglected means to improve prognosis. They are the healthiest cardiovascular intervention. Even cardiologists focus on pharmacological treatment and evaluate classical risk factors without asking about daily exercise or objective measures of physical capacity. It is surprising considering the strong data that underscores the survival benefit of regular exercise training.

Some kids are being misdiagnosed with asthma

Vocal cord dysfunction (VCD) is the sudden, abnormal narrowing of the vocal cords during inhalation causing obstruction of the airflow, and is characterized by a noise that can mimic the sound of wheezing.

Discovery of novel cause of iron overload in patients with thalassemia

According to the study, thalassemia patients overproduce a protein called GDF15, which suppresses the production of a liver protein, hepcidin, which in turn leads to an increase in the uptake of dietary iron in the gut.

Protein on the surface of platelets plays a key role in cancer-induced platelet aggregation

Scientists have provided new details about how cancer cells spread by surrounding themselves with platelets – the blood cells needed for blood clotting.

Big leap in genomic screening of blood vessels from patient tissue

Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing.

Stroke outcome improves when patients continue taking cholesterol-lowering drugs

A new study has illustrated the risks involved when statin treatment is discontinued after a stroke and shows an increased risk of death or dependency is present for up to 90 days.

New findings on vocal cord dysfunction

Vocal cord dysfunction (VCD) is the sudden, abnormal narrowing closure of the vocal cords during inhalation causing obstruction of the airflow, and is characterized by a noise that can mimic the sound of wheezing. A VCD attack can easily be mistaken for an asthma attack though it does not respond to asthma medications.

Binding up iron in the brain to combat Parkinson's and Alzheimer's

Duke University chemists are developing ways to bind up iron in the brain to combat the neurological devastation of Parkinson's and Alzheimer's diseases.

Light may play a much more important role in bacterial life than has previously thought

The bacteria that cause brucellosis can sense light and use the information to regulate their virulence, according to a study in the August 24 issue of the journal Science.
